could not find masir, please make sure it is installed befor

Error message

could not find masir, please make sure it is installed before using the --masir flag

What it means

Thrown by komorebic's startup prerequisite checks when the user passed --masir but the `which` lookup cannot locate a masir executable on PATH. It is a guard against silently launching a companion process that does not exist; masir (the bar/companion binary) must be installed separately from komorebi.

Solutions

1. Install masir (e.g. `winget install LGUG2Z.masir` or via scoop) and ensure it is on PATH
2. Remove the --masir flag if masir is not needed
3. If masir is installed, verify PATH includes its directory or reinstall it
